AUDIO WIRELESS AC224 ANTENNA COMBINER AND DISTRIBUTION MODULE

The AC224 Antenna Combiner and Distribution Module is a 2-zone antenna combining, RF and DC power distribution module. Designed for where the weight and size matters without sacrificing on performance. The AC224 is a 2×2 IN and 2×4 OUT active antenna combiner and distribution system with in-built front-end low-loss band-pass filtering, LNA and user-adjustable gain stage at each antenna input. The AC224 enables the user to cover 2-zone wider area for cart and trolley set-up applications with improved RF coverage and performance and provides a tidy solution in sound bag applications as a 2×1 IN and 2×4 OUT RF distribution module. There are four BNC antenna input connectors that enable the use of standard low loss RF extension cables, and there are eight SMA connectors feeding the diversity receivers. Each antenna input can be individually turned ON/OFF via the display menu when not used, a LED indicator also showing the status of each antenna input. In applications when remote antenna powering is needed, the AC224 offers individually switchable remote antenna powering with LEDs indicating power status. The active antenna powering can be turned ON/OFF through the display menu. The AC224 has a very high input signal handling capacity with very low noise figure and offers an outstanding inter-modulation performance when compared to other low power devices available. The frequency range is custom tuned to customer’s order, the front-end band-pass-filter design is a very low-loss with a very high selectivity at lower and upper frequencies, each antenna input gain is individually user adjustable in 1dB steps between 6dB to -10dB, the AC224 is compatible with full-digital, digital-hybrid and analogue radio microphone receivers available in the industry. A large colour TFT display is used offering a user selectable colour combinations to suit the lighting and visibility. Brightness may be adjusted through the display menu to suit visibility. The AC224 is externally powered between 10-18VDC, the DC input is an industry standard 4-pin HRS and the DC distribution with 4x HRS DC output connectors for powering auxiliary equipment. Each DC output port can be individually turned ON/OFF through the display menu, a voltmeter continuously monitors the dc input voltage.   FEATURES: 2-zone combiner, RF and DC distribution system four antennas feed up to four diversity receivers custom tuned band-pass filtering at each antenna input remote antenna powering at each antenna input independent 4x HRS DC outputs user-adjustable system gain at each antenna input BNC industry standard connectors intuitive colour TFT display menu and LED indicators single DC power source solution soft master ON-OFF switch continuous system volts monitoring soft ON/OFF switch for each antenna input LNA gain settings soft ON/OFF switch for each remote antenna powering settings soft ON/OFF switch for each DC output port settings custom CNC machined aluminium design, lightweight and rugged that fits neatly in any sound cart, trolley and sound bag RF COMBINER/DISTRIBUTION SECTION: frequency range: 470 to 1164 MHz (specify band at order) input impedance: 50 Ohm output impedance: 50 Ohm gain: user adjustable 6dB to -10dB in 1dB steps current consumption: 300mA /-20mA @12Vdc (depends on display brightness setting)   UHF BANDPASS TYPE: available bandwidths: 470-700 MHz, 470-654 MHz, 470-608 MHz, 510-698 MHz, 512-614 MHz OIP3: >41dBm port to port isolation: >20dB noise figure: <3dB   LED INDICATORS: GREEN: antenna LNA is ON RED: active antenna powering and LNA ON NO LED Light: antenna input is OFF   CONNECTIONS: RF inputs: 4x 50 Ohm BNC sockets RF outputs to receivers: 8x 50 Ohm SMA sockets DC Power IN: 4-pin Push-Pull (Hirose compatible) socket, fused and protected against reverse polarity, 10-18Vdc DC Power OUT: 4x 4-pin Push-Pull (Hirose compatible) sockets, individually fused and protected against reverse polarity.
